Abstract
A process for producing geometric shaped catalyst bodies K whose active material is a multielement oxide which comprises the element Mo, the elements Bi and/or V and one or more of the elements Co, Ni, Fe, Cu and alkali metals, in which sources of the different elements are used to obtain a finely divided mixture which is coarsened to a powder by press agglomeration, the coarsened powder is used to form, by press agglomeration, shaped bodies V which are separated into undamaged shaped bodies Vand into damaged shaped bodies V, the undamaged shaped bodies Vare converted by thermal treatment to the shaped catalyst bodies K, and the damaged shaped bodies Vare comminuted and recycled into the obtaining of the finely divided mixture.
